C. Why does MIPS not have add label dst, label srcl, label src2,instructions in its ISA (there are at least two reasons for this)? [Read thisinstruction's function as M[label_dst] = M[label_src1] + M[label_src2].] Provide aconcrete technical justification-you should have ideas both from lab andlecture.

:- We will be implementing a new instruction within the MIPS architecture. New instruction will decrement a Variable stored in a memory location and store the decremented value in a register (Rt). This new instruction will be called DECR. Its usage and interpretation is Usage: DECR Offset(4*Rs),Rt Interpretation: Reg[Rt]= Mem[4*Rs+Offset] - 1 Which blocks are used and which control signals are generated for this instruction. How would the Instruction code fields look like ? Do we need to add an extra hardware logic, explain ? (You may draw a simplified datapath flow)
In generall, computers think in terms of numbers (i.e. binary data). Thus, any operation performed in the computer must be done using either mathematical or logical operations. Given this inherit limitation of computers, what is the compare instruction actually doing when we, as assembly programmers, provide two numbers for it to "compare"? Furthermore, what assembly instruction is similar to the compare instruction? How are the two instructions different?
For sub $rd, $rs, $rtReg[rd] = Reg[rs] + Reg[rt] - Which resources (blocks) perform a useful function for the given instructions? - Use the following diagram for each instruction and trace its flow(use pen or highlighter) for the execution of that instruction. - List the units that are used for each instruction. (I mainly need help with tracing, please and thank you)
Draw a diagram showing the relationship of the EDX, DX, DL and DH registers. Page 29 shows EAX that you can follow as a template. Template attached
Can you explain please
(a) In MIPS machine language, the R format instructions need an additional field (the “funct” field) to specify the instruction type (“add”, “sub”, etc.). Why can’t this be done using just the 6-bit “op” field, which all MIPS instructions have, instead? (b) Give a sequence of MIPS assembly language instructions that adds the contents of $s0 and $s1, storing the result into $s0, if the contents of $s1 are greater than 6. Otherwise, the contents of $s0 should be incremented by 28. In either case, afterwards the contents of $s0 should be copied into $s2. (c) Suppose that the starting address of an array of words is stored in $s0. Give a MIPS assembly language instruction that loads the contents of the second word in the array into $s1. (d) Suppose that A and B are defined using “A: .word 0”, and “B: .space 100”. Give a sequence of MIPS assembly language instructions that calls a procedure “P” with its two arguments being the contents of A and the address of B, using the standard procedure…
E In the following code block(Reference:Q11), you will a set of assembly instructions with corresponding line numbers (line numbers are for informational purpose only and they are not part of the source code). 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 mov edx, 5 dec ecx jmp LABEL1 mov eax, 1 LABEL1: mul edx jmp ecx mov edx, 0678h sub edx, eax jmp DWORD PTR [edx] neg ebx add ecx, ebx mov eax, 0 For each of the conditions/scenario listed below, indicate the corresponding line number (that cause or is associated with the condition/scenario). Enter 0 (Zero) if the condition is not caused by the block of code. 1) Memory indirect jump: type your answer... type your answer... type your answer... type your answer... 2) Register indirect jump: 3) Relative short jump: type your answer... 5) Two's complement type your answer... 4) Relative near jump: 6) Unreachable code
